Sensitivities of one-prong tau branching fractions to tau neutrino mass, mixing, and anomalous charged current couplings
Maria Teresa Dova, John Swain, Lucas Taylor
We analyse the sensitivities of exclusive one-prong tau branching fractions to: the tau neutrino mass; its mixing with a fourth generation neutrino; the weak charged current magnet…

First unitarity-independent determination of the CKM matrix elements , , and ${V_{tb}$ and the implications for unitarity
John Swain, Lucas Taylor
The magnitudes of the CKM matrix elements , , and are determined for the first time without any assumptions of unitarity. The implications for the unitarit…

New constraints on the tau neutrino mass and fourth generation mixing
John Swain, Lucas Taylor
We present new constraints on the mass of the tau neutrino and its mixing with a fourth generation neutrino. From an analysis of the partial widths of tau lepton decays w…
